Peter and Carol opened the door to see carpeted room with several shelves built into with DVDs with several movies that they had seen in theaters and several other movies they had heard about but the two did not have the chance to see because of lack of time. There was also a shelf that had glass windows along with a keyhole. Given that the plaque above that shelf stated 'Absolutely Not For Children!!!' Peter and Carol had a good idea that these were adult movies.
Or more accurately Porn.
At one end of the room was quite possibly the largest screen they had seen in their lives along with the DVD player to play the movies.
There was also seats that were made for two, three, or four people to cuddle in on as well as posters of movies on the walls which told the two that this was a movie room. One such poster was starting to change show a sci-fi poster with Carol, Emma, and Sue in the slave outfit of Star Wars infamy that Leia wore at the beginning of Return of the Jedi.
Peter and Carol couldn't help but wonder if the house had any of those slave bikinis stored around.
They could see a couple of doors which one was open as they could a dining table with chairs surrounding it so that was probably the dining room. Peter and Carol looked around and saw a door in the dining room along with a serving platform cut into the wall that most likely indicated that door led to the kitchen.
